45598513 ÷ 635 
The aim is to understand the frequency of 635 in 45598513.

On to step 1:
635 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 635

Let's proceed to step 2:
635 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 635

Step 3:
455 divided by 635 is 0 with a remainder of 455.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 455 and we're left with 455.
Fetch the next digit (9) from the dividend, attach it to 455 and continue: 4559 / 635

Let's proceed to step 4:
635 goes into 4559 7 times with a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 4445 from 4559 and we're left with 114.
Append the next digit (8) from the dividend to 114 and continue with: 1148 / 635

Advancing to step 5:
635 goes into 1148 1 times with a remainder of 513.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 635 away from 1148, we end up with 513.
Grab the next digit (5) from the dividend, add it to 513, then carry on: 5135 / 635

Step 6:
When dividing 5135 by 635, we get 8 with a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 718.0
If we subtract 5080 from 5135, we get 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 635

Going ahead to step 7:
551 divided by 635 is 0 with a remainder of 551.
Write down 0 as next digit of the result. 
Result so far: 7180.0
The remainder is 551 after subtracting 0 from 551.
Include the next digit (3) from the dividend after 551, then repeat: 5513 / 635

Going ahead to step 8:
635 goes into 5513 8 times with a remainder of 433.
Record the quotient 8 as the next digit in the result. 
Result so far: 71808.0
The remainder is 433 after subtracting 5080 from 5513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

On to step 9:
The number 635 fits into 4330 6 times, leaving a remainder of 520.
The next digit of our result is 6. 
Result so far: 71808.6
The remainder is 520 after subtracting 3810 from 4330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 10:
635 can be fit into 5200 8 times, resulting in a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 71808.68
If we take 5080 away from 5200, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
1200 divided by 635 is 1 with a remainder of 565.
Use 1 as the next digit of our solution. 
Result so far: 71808.681
The remainder is 565 after subtracting 635 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 12:
5650 divided by 635 is 8 with a remainder of 570.
Put 8 as the next digit of the answer. 
Result so far: 71808.6818
If we subtract 5080 from 5650, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 13:
If we divide 5700 by 635, we get 8 and a remainder of 620.
Put 8 as the next digit of the answer. 
Result so far: 71808.68188
Deduct 5080 from 5700 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final result is 71808.68188 with a remainder of 0.00062.
